DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data recording / reproducing system, a reproducing method thereof, and a storage medium storing a program thereof. The present invention relates to a data recording / reproducing system which is preferably applied, a reproducing method thereof, and a storage medium storing a program thereof.

[0002]

2. Description of the Related Art Broadcasting companies must manage various kinds of broadcasting materials such as video and audio produced inside and outside a station and transmit them accurately at a predetermined time according to a playlist or a program schedule. . In particular, general broadcasters, which are abbreviated as "private broadcasts", must deal with a large amount of commercial materials in addition to program data, so that the complexity of material management and transmission control cannot be denied.

[0003] For example, in the case of a commercial video (hereinafter, abbreviated as a CM), unification work for sequentially recording CM materials on a VTR tape is performed according to a playlist in which a transmission order for one day is described. After creating a tape for transmission called "unified tape", as a rehearsal before sending, perform a work called "on-air preview" to check the contents of the CM material recorded on the unified tape. Then, the unified tape is set in the transmitting device and transmitted according to the playlist or the program schedule. Here, in the on-air preview operation, specifically, the unified tape is inserted into a VTR (Video Tape Recorder) and played back, and the operator refers to the playlist at hand and arranges the CMs in a regular sequence. It was checked whether they were recorded in order.

[0004]

However, since the magnetic tape medium used for the above-mentioned unified tape is a storage medium that cannot be randomly accessed, a specific CM material is searched for in the on-air preview operation. And C
When reproducing an arbitrary portion of the M material, the tape must be fast-forwarded (or rewound). Since it cannot be accommodated, it is necessary to perform an operation such as replacing a tape on the way, and there is a problem that the operation efficiency of the on-air preview is extremely low.

[0005] In general, since the above-mentioned tape is reused and repeatedly recorded and reproduced many times, in addition to the work of confirming the order of CMs, which is the original purpose of the on-air preview, deterioration of the tape itself is caused. Whether it has not occurred,
In addition, it was necessary to check whether or not the CM material was flawed, which required a great deal of labor and time. In this case, if the only task is to check the order of the CMs, the preview can be performed at high speed by using the variable speed function (Variable function) such as double speed and fast forward attached to the VTR. In order to confirm the deterioration state of the material and the flaws in the material, it was inevitable to perform the preview at the same reproduction speed (1 × speed) as that at the time of broadcasting.

Further, since the order of CMs recorded on the unified tape is recorded in accordance with the playlist, when the playlist is changed, the changed CM material is re-recorded, There is a problem that the re-created unified tape must be further previewed to check the contents. Therefore, the arrangement of CMs along the playlist can be checked (previewed) at a high speed, and a desired CM material can be found at the beginning, and a CUEUP (cue-up; specified designated It has been required to realize a broadcast system that can perform playback at a time from a playback start point) and can flexibly cope with a change in a playlist.

In recent years, from the viewpoint of the spread of multi-channel broadcasting by CATV (cable television) and the like and the efficiency of the broadcasting operation itself, a hard disk has been replaced with a sequential (linear) recording and reproducing using a conventional VTR tape. A video server that can record, reproduce, and edit video and audio data using a random access (or non-linear access) storage medium such as a (HD) or magneto-optical disk, or an AV (Audio) and
/ or Video) A device called a server is spreading.

Generally, a video server installed in a broadcasting station has extremely high demands for image quality and sound quality. It is required that there be. Therefore, by using a data recording / reproducing device including a plurality of hard disk devices for recording / reproducing video / audio data in a time-division manner, an attempt to increase the data transfer rate and to increase the capacity has been made. By recording the data, reliability is ensured even if one of the hard disk devices fails.

[0009] Thereby, according to the contents of a program or a broadcasting form which a broadcaster intends to produce, material data composed of a plurality of audio / video data recorded in a distributed manner can be efficiently edited, Also, by simultaneously transmitting multiple channels of the same material data, or by playing back multiple channels at different playback times, a system such as VOD (video on demand) or NVOD (near video on demand) can be constructed. A multi-channel video server capable of supporting various usage forms has been realized.

The data storage / reproducing apparatus used for such a video server includes a technical paper ("A Case for Redundant") published by Patterson et al.
Arrays of Inexpensive Disks (RAID) ”, ACM SIGMOND C
onference, Chicago, III, Jun. 1-3, 1988.), which is configured by arranging a plurality of hard disk drives (HDDs) each including a plurality of hard disks.
AID (Redundant Arrays of Inexpensive Disks) technology is used.

Next, the overall processing operation in the CM bank system according to the present embodiment will be described. First,
Material data such as CMs produced inside or outside the station is stored in a portable storage medium such as a magnetic tape, and is sent to a department (for example, an editing department or a sales department) of a broadcasting company that broadcasts the material data. Delivered (this is conveniently referred to as the "arrival"). Note that the arrival is not limited to the portable storage medium. The arrival using communication lines such as exclusive lines,
That is, although there may be a receipt of only data, for the sake of simplicity, the following description will be made by taking a receipt using a portable storage medium as an example.

When the goods arrive, the person in charge of the department will
A terminal belonging to the host management system 101 is operated to execute a reception process for each material data. In this reception process, a material code for uniquely identifying each material data is assigned. The material code must be a unique and unique code that is unique and unique. The format of the material code can be, for example, a combination of an appropriate prefix and a multi-digit serial number. The prefix may include an appropriate character (or character string) representing the type of the material code, and may be, for example, “CM” for a CM material. Then, a unique material code can be set by automatically generating a serial number while automatically counting up. A specific example will be described later.

In the reception process, in addition to the assignment of the material code, various attribute data relating to the material data are input to create a play list. The attribute data includes, for example, the length (DUR) of the material data, the name of the material data provider (sponsor name), the name of the material data (material name),
The types of audio data included in the material data (monaural, stereo, etc.), the types of video data included in the material data (NTSC, PAL, etc.), etc.

Next, when the reception processing in the upper management system 101 is completed, the play list including the material code and the attribute data is transferred from the reception management system 101 via the data gateway 102 and created in the database server 301. Is registered in the database table. For example, the upper management system 10

As described above, the playlist is created in the editing department or the sales department where the upper management system 101 is installed, and is registered in the database server 301 via the data gateway 102 as needed. The change of the playlist is also determined on the upper management system 101 side, and the replacement data (updated playlist) is
Received by data gateway 102. At this time, the protocol or the like of the received data is checked, and if the protocol matches, the database server 301
The update (original) data registered in the database server 301 is updated, a change notification issuance request is output to the change monitoring area created in the database server 301, and a change monitoring flag is set in the change monitoring area.

On the other hand, the change monitoring server 302 installed in the database subsystem 300 constantly monitors the change monitoring area created in the database server 301, and changes the change monitoring flag in accordance with the registration of the updated playlist. When it is detected that is set, for all application programs that refer to the playlist,
Sends a change notification (update information). Specifically, the filing terminal 201, the sending monitoring terminal 203, and the like, as well as the preview terminal 202, incorporate application programs that execute respective work processes with reference to playlists registered in the database server 301. Therefore, the change monitoring server issues a notification signal indicating that the playlist has been updated to the operation terminal incorporating these application programs.

The preview operation performed with reference to the updated play list is the same as the processing procedure of the above-described preview method, and a description thereof will be omitted. Therefore, if the playlist created already is changed just before transmission (for example, the day before the broadcast), the preview method using the unified tape shown in the prior art will update all the CM materials with the updated playlist. Record again according to the list,
Preview the recreated unified tape further,
While the content must be checked, according to the preview method to which the playlist change monitoring control processing according to the present embodiment is applied, the upper management system 101 updates the database server 301 via the data gateway 102. When the registered playlist is registered, the change monitoring server issues a change notification and the latest playlist is immediately displayed on the monitor screen of the preview terminal.

Therefore, the operator can immediately recognize the change of the playlist and click on the updated CM frame or CM material to instantaneously reproduce the image under the predetermined reproduction operation condition, and the operation can be performed in a very short time. Can be used to confirm the contents of the changed data. Note that the change monitoring control function executed by the change monitoring server 302 as described above is also realized by using the program function of the database server 301.

The processing procedure of the preview method and the processing procedure of the change monitoring control according to the present embodiment described above store a program for executing the same in a storage medium and are introduced into an existing CM bank system or newly introduced. The data recording / reproducing system and the reproducing method thereof according to the present invention can be easily realized by incorporating them into various operation terminals including a preview terminal constituting the CM bank system, a database server, a data gateway, and the like.

Here, the storage medium is not limited to a portable type such as a general floppy disk, CD-ROM, memory card, ROM chip, etc., but is stored in a fixed storage device (hard disk) in advance. May be installed and provided. Further, when the program is distributed via a network or a communication line, a storage device of a distribution source is also included in the storage medium. Therefore, the program stored in the above-described storage medium is in a format executable by a hardware system built in or attached to a preview terminal, a database server, a data gateway, or the like provided in a data recording / reproducing system (CM bank system). Loaded,
By executing the program, the preview method and the change monitoring process are realized by software control.
